Application filed February 13. 1907. Serial No. 357.147.

To all whom it may concern:

Be it known that I, CARLOS D. MYERS, residing at Cleveland, in thecounty of Guyahoga and State of Ohio, have invented a certain new anduseful Improvement in Knot- Tying Apparatus for Bags, &c., of which thefollowing is a full, clear, and exact description, reference being hadto the accompanyin drawingsr y invention relates to an apparatus fortying knots and more especially to anapparatus which is adapted fortying knots around the necks of bags or like objects.

The objects of the invention are to provide an apparatus wherein suchknots may be quickly and firmly formed around the mouth of a bag orsimilar object, and to provide means whereby this result may be embodiedin aneconomical and effective apparatus. I accomplish these results byan embodiment of my invention disclosed in the drawings forming parthereof, wherein F i re 1 represents a pers ective view of the 'e membersor blocks W erein the knot is formed and the stand for supportin thesame. Fig. 2 represents anelevation o the combined carrier and twinefeeding device. Fig. 3 represents a portion of a bag showing the neckthereof secured by means of'a knot formed by my apparatus. Fi 4represents an enlarged perspective detai of one of the die members inwhich the knot is formed.

' shaping 0 Fig. 5 re resents a lan view of the complete die, the andlesan suplports -being omitted, the passageway being s own in dotted lines;and Fig. 6 represents a view, partly in elevation and partly in section,of the flexible carrier or device for threading the twine through anddepositing the same within the passageways of the die.

Describing the parts by reference characters, 1 represents a stand, tothe u per end of which are. pivoted two die mem ers '2 and 3 ,eachmember belng provided with an operating handle 4. Theoplposing faces oft die members have each t erein a fractional recess 5 for the receptionof the neck 5 of the bag or other object to be'tied. Each die member haswithin the same fractional assageways adapted,when the two die mem ersare brought face to face, to form acomplete tortuous assageway for thereception, and

i the twine to form-a knot therein.

The passageways are so arranged that the knot formed shall preferably bea knotknown as a clove-hitch,a knot of this character bemg shown in Fi3. In forming such hitch, lt is necessary t at the two ends 6 and 7 ofthe twine shall be engaged and held securely in place by the portion 8of the twine which crosses the same. To provide for forming a knot ofthe character shown in Fig. 3, it is necessary to form assageways in thetwo die members in suc ll manner that, if twine were threadedtherethrough, the twine within the die would assume substantially theshape shown in Fig. 3. Furthermore, it is necessary that when the twineis tautened it shall be free to pass through the body of the die intoengagement with the neck of the bag which is inserted within thecomplete recess formed by fractional recesses 5. To accomplish thisresult, I form in one of the die members or blocks fractionalpassageways which shall contain the parts 6, 7, and 8. The die member 2is shown as having therein the fractional passageways which will formsuch parts 6, 7, and 8'which constitute the hitch proper of the knot.The other die member or block is provided with a pair of parallelfractional passageways wherein the straight portions of the loops orbights of the knot are formed.

In constructing the die, I form a piece of tubing, preferably brass,into the shape of the desired knot (in this case a clove-hitch) and castthe metal of the die around the tub-.

ing, whereby the passageway for the knot is provided within the tubing.In casting, the two die sections or members may be formed separately,tbysuitable spacing means placed in themold to avoidthe necessity of sawingor otherwisecutting the die in two. By use of a suitable core, thefractional recesses 5 will be cast in the die members. In order topermit. the twine to come through the die members into engagementwiththe neck of thebag or, other object which is to be tied,-

I connect the fractional passageways with the inner faces of the diemembers to enable 1 the twine to pass therethrough when the sameistautened to form the knot.

As the die member 2 is the one wherein the hitch proper is formed, Iwill describe the. passageways formed therein.

6 denotes the passageway whereinto the Fig. 4 at 6", 7 and, 8

twine is inserted in the die member-2, and 6 denotes the correspondingpassageway in the-die member 3.

a 8 denotes the passageway 1n the die member 2 wherein provision is madefor the part 8 of the knot to cross overthe part 6 and 7, and 8represents the corresponding passageway in the die member'3.

' 7 denotes the passageway in'the die member 2 which corresponds to theportion 7 of the knot. This latter passageway, as will appearparticularlyfrom Fig. 4, passes within (or, in the completed knot,under) assageway 8, and emerges from the end the die member 2 which isop site the inlet and 6 for .the. insertion of t e twine. At this end,suitable grippin hereinafter) is provi to "prevent the same from beinthrough the passageways of the ed for holding the twine ie when tensionis applied to the twine to knot the same around the neck of the bag.

The passageways in the die members communicate with the fractionalopenings therein by means of fractional channels, said channels being ofconsiderably less width than the diameters of the pass eways,

ing sufficient to enab e the twine to pass therethro'ugh the diameter ofthe twine carrier, which will be hereinafter described. These channelsare indicated particularly in connection with as extending respectivelybetween the passageways 6, .7 and 8f,'and the central-opening in the diemem- To enable the twine to be threaded quickly" and positively throughthe passageway in V the die, I provide a combined. feeder and carriertherefor. The carrier proper 9 is composed of a suitable number ofjoined me- 1 tallicelements. In Fig. 6, the carrier is shown, saidcarrier consisting of a suitable number of tubular sectionslfleachhaving a flange 1 1 at opposite ends thereof, the flanges ofadjacent sections being connected by means of ametallic coupling 12,which 1s generally rounded orspherical in shape and flexibly embracessaid flanges. The front end of the carrier 9 consists of an elongatedmember 12 having therein a pair of spring clips 13 adapted to engage theforward end of the twine 14 and prevent it from being dropped by thecarrier in its travel through the passageway of the die. The angle at.which the clamps 13 engage the twins permits them to slide over thetwine when the carrier is'withdrawn from the passageway of the die, theend of the twine being engaged by the gripping device on the rear end ofthe die.

To facilitate the application of the carrier proper to the tortuouspassageway oi the die and to feed the twine to said carrier, 1 empioy asupport comprising" a stem 15 con-- means (to be described withdrawn thewidth beand said widthbeing less than nected to one end of saidcarrier,said stem having a central bore or passageway for twinecommunicating'with the bore of the carrier. vided with an operatinghandle 16, and said handle may be provided with a spindle 17 whereon ismounted a spool 18 on which the twine is wound. To deposit'the twinewithin the passageway as the carrier is withdrawn and apply tensionthereto sufiicient to knot the same around the neck illustrated as"consisting of a spring 19 attached to the stem and having a down.

twine and press the same against t site surface of the borein 15. Bymeans of a screw 21' extending through said spring and threaded into 15,the tenslon of spring 19 may be adjusted to any desired extent.

.To facilitate the application to and employment of the parts 9 and15with the die, I

and supporting tube or member 22 which is spaced 'a short passageway 6.x Tube 22 is sufliciently'longer than ,9 to accommodate the entirelength of withdrawal of said 9 .and 15 from tube 22, thelatter isprovided with stopbeing shown as a lon pin 25" projecting from 15 intosaid slot.

slot 24 in 22 and a there provided a which the twinemay be severed after9 has been withdrawn from the die.-

refation to the rear endfof the sageway therethrough is the hereinbeforereferred to.

die-block or member 2 aving its stem 27 in a casing '27, carried by saidblock or memher, there being a spring 29 in said casing to yieldingly'hold the plunger in pro er relation to rear end of passageway 6. lunger28 is similarly mounted on block or member 3 havin a spring therein (notshown).

' Wit the arts arranged and constructed as shown, t e operation will beobvious. 'The operator opens the die and inserts the neck of the bag orother object to be tied and then closes the'said membersjt'pgether.Grasping the handle 16, he forces the-carrier 1 through the tortuouspassageway of the die.

of a bagor around any other article insertedinto the recess 5, I providea tension device which is At the rear side of the die and in operativeThe other end of the stem is pro-- ward projection 20 adapted to englagethe e oppo provide member 2 with a combined guiding secured to saidmember 2,as by means of a bracket 23, with its mouth opposite to anddistance from. fractional 5 the latter therein and to prevent accidentala stop for 15, such tween'innerend of-22 and front face of 2 knife 26 bymeans of-' shown as comprising two oppositely located of the carrier 9.Plun er 27'is mounted on v and is provided w th a similar caslng- 28between the central portions of thet'members As end member 12* strikesthe beveled or concave faces of plungers 27 and 28, it forces them apartand deposits the end of the twine between the same. On the reverse move--ment, the end of the twine is firmly gripped between 27 and 28 and willbe threadedthrough the carrier, the angle of sprin s 13 permitting thisaction, and deposited within the die. The action of the tension device20 on the twine'will, however, draw the twine through the fractionalchannels 6, 7 and 8 and, by the tim the carrier has been withdrawn fromthe die, a knot will have been formed around the neck 5 of the bag (asshown in Fig. 5) or around any other article that may have been insertedinto recess 5. Knife 26 may then be operated to cut the twine and thedie-blocks opened up, releasing the end of the twine from the plungers27, 28

and permitting the removal of the object around which the knot has beentied.

While the apparatus described herein will ordinarily be employed withtwine, I do not propose to be limited in use to its employment withtwine, as it will be obvious that it may be used with rope (particularly.of small size) flexible wire and the like, .the term twine beinggeneric and covering such other knot-tying material as it may bedesirable to usewith my apparatus. Furthermore,- while it will have alarge field of usefulness intying the necks of bags, I do not propose tobe limited in use to employment with 'loosearticles, as it is obviouslyadapted for use in connection with other articles.
